Hi all

i'm new of visualjforex, and i have a really simple problem:
how detect when 2 EMAs cross eachother? i tried simple: " IF " (logic block) EMA1 == EMA2 , but seems it never happen (even if it cross eachother), cannot understand why. its like if it skip the moment it get equal value....

any help will be appreciated, thanks to all, bye!

Greetings!

It is very rare that these two EMA's have the same value. Both indicators are irrational and if you say that you want to generate a certain signal by setting them to equal it is very seldom that this would ever happen.
You have to find 4 points to "see" a cross:
For example: EMA(40) and EMA (20);


You need to check the two EMA's before and after the cross.
You can also check out the example of a SMA cross by clicking on the blue box of "strategy" after successful login in the Community.

DLEGION,

This is the fun of codeing - you have to look at a problem and descibe it in code. For 2 lines crossing - the best way is to look at the 2 line's previous value : Line A = 100 , Line B = 200 ,,
and if the current value - Line A = 300 and line B = 250 the you can tell that they have crossed.

Example = ( LineA(prev) < LineB(prev) ) and ( LineA(now) > LineB(Now) ;

Visual Jforex is easy when you think about the above.

Enjoy

thanks for the help!
i'm not a programmer as you see, and i respect them everyday more for this job, its not easy "think in a machine way" !
